Mathematica Commands for ln|x| to Accompany Lab I.4 ( calc1-lab4.html )

This time there are 3 commands for you to copy and paste. You may copy all 3 at once, but when you paste them, paste them as ``plain text'', otherwise the blank lines will disappear and that will cause MANY MANY problems for you.

(* (Read the paragraph above before pasting!!) *)

list = Table[{x, ???},{x, -4, 5 , 1/2}];

<< Graphics`MultipleListPlot`   

 MultipleListPlot[
 { {-4,?},{-3,?},{-2,?},{-1,?},{-1/2,?},{1/2,?},
 {1,?},{2,?},{3,?},{4,?},{5,?} },
  list,
 SymbolStyle->{Hue[0.7], Hue[0.9]},  AxesLabel->{x, y},
 Background->GrayLevel[0.9], PlotLegend -> {"Derivative", "Guess"},
 PlotJoined -> {False, True},
 SymbolShape -> {PlotSymbol[Box,3.5], PlotSymbol[Triangle, 5]}
 ];
